You found and idea and stuck to it really well, gotta give you that. While I’m not fan of these kind of exploration/point and click kinda games I had fun for a bit, but I got stuck after the guy just said no. Not sure where could else go, nor do I know why slenderman came into the house, I hope he plays rent.
Graphics wise the game looks okay, web is suffering from lagspikes upon first room inspections, and the text is too fast/sometimes hard to read, but otherwise it conveys the eerie vibe.
Music and sfx were okay, liked the little bitcrushed lines you had sprinkled in there.
Overall a unique concept, well done!
